HOOK.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed January 18, 1905. Serial No. 24:1,535.

To all whom, it may concern:

Be it known that I, THOMAS V. WALLAoE, a citizen of the United States ofAmerica, residing at Monongahela, in .the county of VVashington andState of Pennsylvania, have invented certain new and useful"Improvements in Hooks, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in hooks,and more particularly to that type commonly known as snap-hooks.

This invention has for its object to provide a novel form of hookwherein means is embodied for preventing a link or the like article frombecoming detached from the hook after it has been secured thereon.

Another object of this invention is to provide a hook having a novelform of snap or locking device which will be extremely simple tomanipulate and will be protected from being struck by any object,whereby the link or the like object held upon said hook cannot becomedisengaged therefrom.

With the above and other objects in view reference will be had to thedrawings accompanying this application, wherein like numerals ofreference designate corresponding parts throughout the several views, inwhich-- Figure 1 is a side elevation of my improved hook. Fig. 2 is atop plan view thereof, and Fig. 3 is a perspective View of a hookconstructed in accordance with my invention.

To put my invention into practice, I construct my improved hook of abody portion 1, carrying upon its one end a yoke 2. The body portion ofthe hook has formed therein a substantially bayonet-shaped slot 3, theprovision of this slot forming a substantially hooked-shaped bodyportion. The end of the book, as designated by the reference-numeral 4,is slotted, as indicated at 5, and upon the one side of the slot isformed a lug or shield 6.

The reference-numeral 7 designates a pawl, which is pivotally mounted inthe slot 5 by a pin 8, and this pawl is made of a suflicient size thatthe one end 9 of the pawl will rest upon the body portion of the hookand close the slot 3, while the other end thereof protrudes upwardlyalong the side of the lug or shield 6, whereby it may be easilydepressed in case it is desired to open the slot 3. \Vhen the slot 3 isclosed by the pawl, it lies at an angle to the body portion of the hook,whereby a link 10 or the like article which is secured in the hook willbe prevented from forcing the pawl outwardly and releasing said link orarticle. To normally hold the pawl in the position illustrated in Fig. 1of the drawings, I have provided a flat band-spring 11,

which is secured on the upper face of the end of the hook 4;, asindicated at 12, and the spring is adapted to bear against the pawl andnormally hold it in engagement with the body portion of the hook and ina position which will close the slot 3.

It will be observed from the position of the pawl 7 that the link 10 canbe readily placed in the open end of the slot and pulled upwardly pastthe pawl 7, the pawl receding within the slot until the link has passedinto the loop end of the hook, at which time the pawl will return to itsnormal position and close the slot.

Heretofore in hooks of this type it has been possible to so position thearticle or link being held that with a sudden or spasmodic jerk the linkor article could be removed from the hook, and for this reason I haveconstructed my'improved hook as above described, whereby it will beimpossible to remove the link or article without first depressing thespringpressed pawl 7.

While I have herein shown the book as carrying a yoke, which is thecommon practice in hooks of this type, I desire it to be under-' stoodthat the yoke may be dispensed with and the ordinary eye formed on theend of the hook, whereby it can be carried by a suitable chain or cable.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit and scope of theinvention.

What I claim, and desire to secure by Letters Patent, is

A snap-hook having a hook member, the

outer arm of which is slotted at its free end to against the inner faceof said pawl, substanform two side walls, one of which extends uptiallyas described. I wardly beyond the other and forms a shield, In testimonywhereof I affix my signature in apawl pivoted between said sidewallshaving the presence of two witnesses.
